this culture, the meaning is mutually accepted. the use of symbols is the single most distinguishing feature of any culture. but as distinct as they are, all symbols are used for the same purpose -- to communica, manipulate, and preserve information. the circle of coral symbolizes the night sky. but this lesson depends on the use of language, a symbolic system in which arbitrary sounds are joined together and given meaning. of all symbolic systems, language best communicates very complex ideas. here, celestial navigation is taught on a south pacific island. we begin to learn language and other symbolic systems at birth. in time, they become a part of who we are and how we perceive the world. still, it's difficult for those of us in one culture to fully understand the symbolic systems of another. for archaeologists, the task is even more complex. the cultures they study can no longer be directly observed. archaeologist david webster. webster: suppose i came into this stadium a week, or even a century, after all the people left. how would i figure out what happened here ? what this arena was u
they use. households in such simple economies are almost completely self-sufficient. at the other end of the spectrum are highly complex economies in which people specialize in one particular job, like these shoe salesmen in morocco. specialization means people are no longer self-sufficient, but depend on each other. the shoe salesmen are dependent on the shoemakers, and the shoemakers are dependent on the tanners, and so on. this dependence on others makes society in general more complex, so specialization is a measure of society's overall complexity. archaeologists find evidence of specialization everywhere -- in the buildings and sculpture of ancient cities, and in crafts like elegant jade earrings, decorated pottery and even skulls with jade inlays in their teeth. these craft items were all made by specialists who worked at the ancient maya city of copan. between a.d. 400 and 800, this magnificent city flourished as one of the major centers of maya art and culture. copan was built in a broad mountain valley on the western border of honduras. at its height, the economic system of t

these graphics. what i thought i would do is simply pull some basic terminology out for us, give us some basic language. and i thought i would do it since we are so well educated now, it's about time to kick us all out into the real world and use our six dimensions of religion. i thought i would take our six dimensions of religion, put it in that framework and just, we are not pretending as always that we are learning everything about east asian religion, but what we are trying to do is draw out some key answers to profound life questions here. anyway, looking at the graphics. first off, difficulty number one, if we haven't already listened to some other difficulties for westerners looking at this, we are so used to labeling. but when we think about the picture of chinese religion, it's a combination of confucianism, taoism, and buddhism in the mix, perhaps some christianity, some folk religion. we'd move to japan and we'll see the same set but also with shinto elements in there so it's a full world view, a full lifestyle, we have to keep that in mind even though we are dividing things up. so

capable of language, creativity, and thought. the differences among us lie in our cultures, our beliefs, how we organize our societies and how we make our living. humans have populated every environment on earth. we live on the frozen tundra and in the searing deserts. we live in thriving cities of millions and in isolated camps of a few dozen. some societies seem simple because they are small and their members are self-sufficient and use simple tools. others seem complex because they have large populations and people depend on each other for food and goods and use sophisticated technology. in between, there is a range that fills the spectrum. all of these differences are cultural, learned behavior, the result of a complex interaction between our inventiveness and our natural environments. as we search for new horizons, our inventiveness thrusts us across the boundaries of space, into new worlds. this new view of earth dispels an ancient myopia -- the artificial boundaries of our states and the politics that often divide us. here is a vision of one planet and one family of humankind. bu

, in the early thirties, that sort of thing, 1930s and forties, people used to try atom smashes, used to try to see if they could transmute elements from one kind to another. and one of the reactions that did succeed was kinda novel. instead of throwing higher and higher velocity particles at matter, three people in geany, lisa meitner, otto hahn, otto-- strassman, i think, anyway, what they did was they threw slow moving neutrons at uranium isotopes and they found a reaction that changed the world. and the reaction tt changed the world is that what y see before you here. it's in your textbooks. the first page in the chapter, fission and fusion. and all we're saying is that it turns out if a slow moving neutron taps into uranium 235 isotope-- [makes sounds] --it will lay it right in half, and the isotopes, instead of a little particle coming off like maybe a proton or an alpha particle, the whole things falls on half. wild. and-- [makes sounds] here's a typical reaction. there are many reactions. this is just the typical one. the uranium busts in half into krypton and barium. these are about
elsewhere in youbody, like in the arm. there are also some standard diagnostic procedures used to test for coronary heart disease. a doctor may use several to determine the extent of the disease. goldenetz: the first doctor that ever said anything about coronary to me... it w really funny. judy and i had gone on a cruise, and i got this kind of tightness again and it was almost like my throat though, again. so i went to see the physician on the ship, not really feeling that bad, but i thought, "well, you know, i'll nip it in the bud." i didn't feel good enough to go on one of the tours off the ship. so i went to see the doctor on board the ship, and he gave me an ekg and did some other things. and he says, "anybody ever said anything about a coronary problem to you?" an electrocardiogram (ekg) is a graphic record of the electrical activity the heart as it beats. it can detect abnormal heartbeats, inadequate blood flow and heart enlargement. goldenetz: i then decided, well, i'm gonna get this taken care of one way or another. so i went to my regular family doctor who had seen me a coupl
the average speed by taking the distance divided by the time. that would give us the average speed. and let's suppose every one of us makes careful measurements and we all get the same average speed, okay? but here's the postulate, that no matter how i move, we will still all get the same average speed. well, right here, this is not controversial. you see it go up, you see it go down. you see it go through that particular space and you measure on your watches that particular time. i measured the same thing. i measured the same space, i measure the same time. we all get the same value. i'm gonna repeat. this time, i'm gonna move. i'm gonna look at it and you look at it. i see the same thing as before. i saw the same thing as before, okay? i saw it go straight up and straight down. get into an airplane and flip a coin. what's the path? straight up and down, right? now, get outside the airplane and look at the path. whoosh, whoosh. okay? you guys saw this. watch again. you guys saw it go like this. now, if you get the same speed, you don't, you really saw it moving faster. but if you got the s
harder? is that so? you used to say i'm pulling harder because you see the rope moving this way. that's what you used to say. remember the old days, when you didn't have that spark called what, begin with a f. - physics. - physics, all right? and now you're getting that spark, right? and now you're starting to see the world a little differently. let's try this with a couple of scale. attach this right on here. okay, now you pull that side and we can measure the force, gang, yeah? and i'll pull over here. now you look to see who pulls harder, me on helen or helen on me? and here we go. how do the readings look, gang? huh? which one is harder? how about there? how about there? and what are they, gang? ss, same same. i can't pull on you any harder than you pull on me, okay? and when i touch you-- who's touching you? am i touching her or she touching me? she's touching my hand, i felt it. from my point of view she's touching me. from her point of view i'm touching her. who's touching who? we're touching each other. thank you, helen. my thumb, my forefinger, they're pulling on each other.
not use either of these shots or this one. i don't want to see them together for a while. excellent for lenny's entrance. tighter on the door. excellent. the first setup is from over in here, where we look, we see susan coming up. her space is down in that corner. howard's gonna go this way. lenny's going to hang at the door. the big problem, too, is that the director's line -- the sightline -- is gonna be between susan down there, howard and lenny over here. so everybody's working that side; cameras all over here. right. all right. so when howard and lenny are in here, looking over at susan, they're going to be looking offscreen left. susan, whenever she turns to camera is looking offscreen right. and we just have to make sure that when they finally come together the exits are right, the entrances are right. it's important at a time like this to wear an athletic supporter. i know. ♪ (music plays) okay. thank you. you guys are the best. you've seen the roof. nice plants and stuff, but let's augment it. let's add something. that's one. uh, chairs -- i don't know. let's get a couple
begin with a s. small. watch this. now you know why dick tracy used to say, "he who controls magnetism controls the universe." look at the force of this little dinky magnet compared to the size of the world pulling all these clips up. so we can talk about the magnetic force today, gang, the magnetic force. ain't that neat? okay. this is a pretty powerful magnet. here's a pretty weak magnet. this one is suspended on a point, and it's magnetized. and what do we call it, gang, do you know? begin with c, end with ompass. try it. put it together. compass. compass, excellent. that's a compass. and guess which way it's pointing. north. you know what it's doing? it turns out that the whole world is a great big, begin with m. magnet. magnet. and surrounding that world is a magnetic field and guess what that compass lines up with, begin with m, f, the magnetic field of the earth. and that magnetic field in this room is oriented like this, okay? but what is the source of that magnetism? the source of that magnetism was betrayed years ago, more than 150 years ago by a fellow by the name of hans ch
